Can anyonehelp me understand an issue with ARP logic? I installed a multi-context firewall and did not use the auto mac command. The router showed (for example) for the subinterfaces on the contexts
arp ip x.x.x.30 mac xxxx.xxxx.fee1
arp ip x.x.x.31 mac xxxx.xxxx.fee1
arp ip x.x.x.32 mac xxxx.xxxx.fee1
IP traffic to the various contexts never flowed. I had to implement the auto mac command which gave each context its own MAC. My question is, is it against the logic to have multiple IPs for one MAC? I did not think it was. Why did I have to use teh auto-mac command on the firewall then? Thanks for any info....
